Grebes are fascinating birds that look something like a cross between a loon and a duck. These small waterbirds have legs that are at the back of their body which are perfect for diving and maneuvering through the water.
In Connecticut, there are five different species of grebes that usually make an appearance on an annual basis, with some of them being extremely common, and others being fairly rare. Here is everything you need to know about these five species.
Eared Grebe (Uncommon)
Identification
Eared Grebes are compact looking members of the grebe family displaying a shorter neck than other species in the grouping as well as a shorter bill. In breeding plumage, this species is quite colorful with a black head, neck, and back, orangey brown colored sides, and golden feathers just behind their bright red eye. It’s also worth noting that they have a crested appearance. In nonbreeding plumage they are far less extravagant looking with a dark head and back, white sides, a white throat, and a white underside. Even in nonbreeding plumage, Eared Grebes still have a bright red eye but they do not appear as crested.
Range
Eared Grebes winter in Mexico and the Southwestern United States in addition to the Pacific coast. In spring, they move north and spend the summer in most of the Northern States west of the Mississippi River as well as Southwestern Canada. They have a habit of showing up farther east than expected during migration.
Diet and Foraging Habits
Eared Grebes eat an assortment of different small vertebrates and invertebrates including fish, shrimp, insects, and amphibians. Since they often live in water with a high salt content, brine shrimp are sometimes a staple food item.
Where to Find This Bird
Eared Grebes are typically found in shallow ponds and lakes. Often times, these birds gather in extremely large groups during migration and are regular visitors of salty bodies of water.
Horned Grebe
Identification
Horned Grebes are fairly small members of the grebe family with a short bill. In breeding plumage, Horned Grebes have a black head and wings with rusty reddish brown sides, a bright red eye, and amber colored feathers near their eye, which somewhat resemble horns. Nonbreeding birds have a black top of the head, wings, and back of the neck, but are white everywhere else. They still have a bright red eye in ninbreeding plumage.
Range
Horned Grebes winter in the Southeastern United States, along the Atlantic Coast, and along the Pacific coast from Baja California all the way up to the Aleutian Islands of Alaska. In spring, they move north and breed in Alaska, Western Canada, and some of the northern states that border Canada such as North Dakota and Montana.
Diet and Foraging Habits
Horned Grebes eat a very wide variety of aquatic creatures including small fish, crustaceans, tadpoles and many different species of insects. They will not only eat aquatic insects but also catch them out of the air.
Where to Find This Bird
Horned Grebes breed in shallow lakes and ponds with plenty of vegetation to hide in. During migration, they show up in many different bodies of water ranging from manmade lakes to ponds.
Pied-billed Grebe
Identification
The Pied-billed Grebe is a small and distinctive looking bird with a brown body and white near the tail. The wings and top of the head are darker than the chest and underside. The term “pied-billed” means striped bill, and it’s certainly an apt way to describe the species as the black stripe on the short, wide bill is obvious in breeding adult birds. Nonbreeding birds look generally the same but without as noticeable of a stripe on the bill. One fascinating thing about Pied-billed Grebes is that they can actually control how much of their body is underwater. Sometime they will only have their neck and head above the surface.
Range
Pied-billed Grebes are extremely widespread across the Western Hemisphere with a year-round range in Southern South America, Northern South America, Central America, Mexico, and most of the United States. In summer, Pied-billed Grebes move north and breed in the Northeastern US, as well as the Midwest. They also can be found throughout Southern Canada in summer.
Diet and Foraging Habits
Pied-billed Grebes mostly prey on small fish and crustaceans, but they will also eat snails, tadpoles, and aquatic insects. These birds hunt for food by diving and catching prey items underwater.
Where to Find This Bird
Pied-billed Grebes can be found in slow moving water such as marshes, flooded fields, and ponds.
Red-necked Grebe (Uncommon)
Identification
Red-necked Grebes are quite striking in breeding plumage when they have their namesake rusty red neck as well as distinctive gray and white cheeks. They also a dark gray to black cap, a long yellow bill with a dark tip, and a dark gray to black back. In nonbreeding plumage, this species is much more pale with only light traces of a red neck and white cheeks. In terms of grebes, the Red-necked Grebe is on the more slender side with a longer neck than many other species.
Range
Red-necked Grebes are widespread across the globe with most of North America, parts of Asia, and Europe serving as a native home to this species. In North America, these birds winter along both the Atlantic and Pacific coasts, then make their way into Alaska and Western Canada (in addition to some states in the continental US) to breed.
Diet and Foraging Habits
Red-necked Grebes eat a variety of aquatic animals, most commonly fish, crustaceans, and insects. They will also eat other aquatic invertebrates as well as reptiles and amphibians. This species takes a page out of the loon handbook when it comes to hunting as they will often use sight to locate food in clear water and then actively hunt for it.
Where to Find This Bird
During the breeding months Red-necked Grebes can be found in marshes and shallow lakes. Usually their breeding areas have thick vegetation lining the shore, providing good places to hide. In winter, the coasts of the United States can hold large numbers of these birds just offshore.
Western Grebe (Rare)
Identification
Western Grebes are slender looking waterbirds with a longer neck and bill than many other grebe species. They look the same in both breeding and nonbreeding seasons with dark gray to black on their back, wings, back of the neck, and top of the head. They have a white face and underside with a yellow bill and bright red eye.
Range
True to its name, the Western Grebe is a species of Western North America. They winter along the Pacific coast of Mexico and the United States all the way up to the most Southwestern part of Canada. In summer, they move into the Western half of the US and Canada to breed. Western Grebes are year-round residents in parts of Northern and Central Mexico.
Diet and Foraging Habits
Western Grebes primarily feed on fish, but they also eat other creatures found in the water including crustaceans, amphibians, and insects. This species actively dives for it’s prey and easily moves through the water while hunting.
Where to Find This Bird
In winter, look for Western Grebes in saltwater habitats along the Pacific Coast. In summer, this species utilizes large freshwater lakes to breed in.
Summary
Grebes are unique and fascinating waterbirds that don’t quite fit into any other category. Knowing the habits, range, and key identification features of each of these species can be incredibly useful in knowing what to look for in the field. Hopefully, this article has helped in answering some questions about the grebes of Connecticut.
